In this paper, we consider an extension of the tribonacci polynomial, which we will refer to as the generalized (p, q, r)-tribonacci polynomial, denoted by T-n,T-m (x). We find an explicit formula for T-n,(m) (x), which we use to introduce the incomplete generalized (p, q, r) -tribonacci polynomials and derive several properties. An explicit formula for the generating function of the incomplete generalized polynomials is determined and a combinatorial interpretation is provided yielding further identities.
